Poor neonatal acid–base status in term fetuses with low cerebroplacental ratio

ABSTRACT Objective To determine whether small‐ and appropriate‐for‐gestational‐age (SGA and AGA) term fetuses with a low cerebroplacental ratio (CPR) have worse neonatal acid–base status than those with normal CPR. Methods This was a retrospective study of 2927 term fetuses divided into groups accor...

Description
Summary:ABSTRACT Objective To determine whether small‐ and appropriate‐for‐gestational‐age (SGA and AGA) term fetuses with a low cerebroplacental ratio (CPR) have worse neonatal acid–base status than those with normal CPR. Methods This was a retrospective study of 2927 term fetuses divided into groups according to birth‐weight centile and CPR multiple of the median. The acid–base status at birth as determined by arterial and venous umbilical cord blood pH was compared between weight‐centile groups with and without low CPR. Results CPR was better correlated with umbilical cord blood pH (arterial pH, r2 = 0.008, P
